Description

Technical Field

[0001] This utility model relates to a suitable fixture for plate tensile testing, specifically a fixture solution that expands the scope of material testing and reduces limitations. Background Technology

[0002] Currently, in the rapidly evolving exploration of various applicable tensile tests for materials, problems frequently arise such as the breakage of plate tensile specimens for brittle materials like carbon-based materials and the inability to clamp short plate tensile specimens. These experiments, however, are unavoidable and require a variety of different models and specifications of testing equipment, resulting in significant investment. Therefore, a suitable fixture for plate tensile testing has been designed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the existing technology of plate tensile test specimen testing: the tensile test of brittle materials and short plate tensile test in various environments such as low temperature chamber, room temperature and high temperature furnace of tensile testing machine requires the equipment of multiple corresponding tensile testing machines.

[0004] The technical solution of this utility model is as follows: A suitable fixture for plate tensile testing includes two symmetrical main bodies, characterized in that: each of the two symmetrical main bodies has an inner groove in its middle, and a slotted plate is connected inside each of the two inner grooves; a cover plate is connected to the outer surface of the inner groove; and screws are provided on both sides outside the inner grooves of the two symmetrical main bodies. A through hole is provided in the middle of one end of each main body, and a pin is connected inside the through hole; the pin is connected to the pull rod of the tensile testing machine.

[0005] As a preferred embodiment of this utility model, the main body is plate-shaped, one end of the inner groove is symmetrically arc-shaped, and the inner surface of the inner groove is adapted to the arc shape of the outer surface of the slot plate.

[0006] As a preferred embodiment of the present invention, the slot plate is U-shaped, with an arc-shaped constriction at the opening and a straight groove in the middle. The slot plate is connected to the plate tensile specimen through the arc-shaped constriction and the straight groove.

[0007] As a preferred embodiment of this utility model, the cover plate is plate-shaped, and both ends of the cover plate are provided with through holes. The cover plate is fixed to the main body by screws, thereby fixing the plate tensile sample.

[0008] The working principle and beneficial effects of this utility model are as follows:

[0009] The working principle of this fixture is as follows: symmetrical inner grooves with arc-shaped connecting plates within the clamping plate secure the tensile specimen within the fixture. The cover plate is then closed and the screws are tightened for the test. By replacing the corresponding clamping plates, different sizes of plate tensile specimens can be tested, thus expanding the range of material testing and reducing the limitations of plate tensile specimens. It is suitable for low-temperature, normal-temperature, and high-temperature environments and for testing various sizes of plate tensile specimens. This solves the problem of not being able to clamp brittle material plate tensile specimens and short plate tensile specimens, saving on equipment investment costs. Attached Figure Description

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] Example

[0017] like Figure 1-3 As shown, this embodiment proposes a suitable fixture for plate tensile testing, comprising two symmetrical main bodies; a slotted plate 2 is located inside the main body 1; and a cover plate 3 and screws 4 are mounted on the main body 1.

[0018] Step 1: Installation of a plate tensile specimen using a suitable fixture for a plate tensile test: Select the slot plate 2 that is compatible with the plate tensile specimen 7 and install it in the groove of the main body 1. The plate tensile specimen 7 is installed in the groove of the slot plate 2. The cover plate 3 covers the slot plate 2 and one end of the plate tensile specimen 7. The screw 4 is locked into the through hole of the cover plate 3 and the screw hole of the main body 1. The same operation is performed on the other end of the plate tensile specimen 7. Finally, the two symmetrical fixtures of the main body 1 are installed on the pull rod 5 of the tensile testing machine using the pin 6. This completes the installation of the plate tensile specimen.

[0019] Step 2: The process of the tensile test.

[0020] Step 3: After the tensile test is completed, pull out the pins 6 inserted into the holes of the two symmetrical tensile testing machine pull rods 5 and the main body 1 in sequence, remove the main body 1, loosen the screws 4, remove the cover plate 3, and take out the tensile plate specimen 7 that has been stretched. Repeat the above steps one, two and three to test various types of plate tensile specimens 7, such as brittle materials and short shapes.

[0021] This type of clamping fixture for plate tensile testing is applicable to plate tensile testing in low-temperature chambers, room temperature chambers, and high-temperature furnaces of tensile testing machines. It can test various sizes of plate tensile specimens 7. By changing the corresponding groove plate 2, it can be adapted to the curvature of the plate tensile specimen 7 to be tested. This clamping fixture is convenient to install and highly versatile. It is made of high-strength steel, has a small size, and is suitable for rod clamping in high and low temperature chambers, thus adapting to different ambient temperatures. By changing the groove plate 2 of various sizes, it can be used to test various sizes of plate tensile specimens 7. It solves the problem of not being able to clamp brittle material plate tensile specimens and short plate tensile specimens, saving equipment investment costs.
